A question about a recipe: Moroccan Tilapia with Red Pepper, Lemon and Quinoa

I have a question about the recipe "Moroccan Tilapia with Red Pepper, Lemon and Quinoa" from marietta brill. Why is 1/2 cup of quinoa listed twice? Is this an error? The recipe instructions don't mention two seperate 1/2-cup portions of quinoa being used at any point.
